Application filed June 7, 1915. Serial Io. 82,634.

To all'wkom it may concern:

Be it known that I, Jomv T. Woorsnr, a citizen of the United States,residing at Kansas City, in the county of Wyandotte and State of Kansas,have invented certain new and umful Improvements in Float- RegulatedSkimmers of which the followiig is a full, clear, and exact description,su

.aswillenable skilledintheartto m which it appertains to make and usethe same.

The invention relates to skimmers for steam generators and seeks toprovide a simle 811:]. form of slnmme' d tlilz'hlch may ced in generatoran receiving ori ce maintained always at an elevation near the surfaf ceofgieethvzaterttii receig'eeha uanti 0 water t r wi any iiient gsubstance that will not evaporate mandconductthesametoaveselwhereit maybe precipitated, and from which the water may return to the generator bythermo-siphon.

ItisnotnewtoinstaIl'sEmmersinsteam generators to remove a portion of theforeignsubstancefromthewaterbythermom' hon and precipitation, but thedesired rehavenotbeenfullyrealized owingtomostdevicsofthiskindbeingfixedrigldly so as to elevation and theconstruction not be- \ingsnchastoreachasuficient amount of thesurfaceofthewater.

Itisesentialthattheskimmer reacha considerable length of the so astodrawfromallparisofthesurface nd that the weight be supported by thewater so that the receiving 0 may be alwayssubmergedbutnearthesurfacewhere the sedimentisfimcarriedbythesteamthatisgen- 4qeratedinthewaterinorderthatthe sediment may enterthe skimmer before it has timetosettleonthefluesorshellofthe The presentinvention seeks to provide an improved automatically adjusting skimmerfor dean: generators, supported y a float, andmeanswpreventthe float andskimmer fimnsettlmgtotoogreata depthwhenthe water is removed from tor.

A further objed: of the invention is to distribute the receivingorifices throughout a considerable length of the generator and provideduplicate outlets near the center thereof, so that a surface may begreater morefrcelydrawnfromandag ter tity of sediment removed from thegenerator.

A still further object is to so construct the skimmer that it is easilyinstalled, and so that the parts cannot become misplaced by the risingand f of the skimmer due to the changes in elevation of the surface ofthe water in the generator.

Withthese and other objects in view the invention consists in theimproved features of construction, connections, combinations and ts ofparts hereinafter de E mnsdtnted $515 wings an more inted out in theappended claims. I P0 In the drawings:Figure 1 is a view in elevation ofa steam generator with a portion of the shell broken away to illustratethe location and attachment of the improved skimmer which is attached,the view also representing the pipe connection to a fragment of aprecipitator which is employed in connectionwiththeskimmerbutisnopart ofthe present invention. Fig. -2 is an exilargcd we .view' of the improvedskimmer. ig. 3 is a still further enlarged fragmentary view of the hingeconnection of the skimmer with the connecting nut broken away to showthe pipe connection.

Connected to and extending downward the generator 1 is a vertical pipe2, the lower end of which is connected to the T 3, thelatterbeingthreaded on each end thereof, while abutting each end of theT is a horizontal pipe & with a collar 5 preferably integral therewith,the not 7 being constructed to slide over the coIlar 5 and screw on thethreaded end of the T and the nut beinglocked ontheTby the tight pin 8,the collar 5 loosely fitting the nut allowing the pipe 4 to turn thereinforming a huge.

The pipe 9 is connected to pipe 4 by Ts 10, pipes 11 and elbows 12 andhas therein a n r of openings on the top 100 thereof adapted to admitwater together with any sediment or substance that hasrisenwiththesteamtothesurfaceofthe water, the float 13 being preferablyconnectedtotheskimmingpipeilbybrazingas shown at 14, but any othersuitable connection may be substituted therefor, theskimmingpipe9beingsecuredtothefloat13insuchamannerastoremainjustbelowthe surface of the water at all time.

Mounted on the top of the float 13 is a yoke 15 which is preferablybrazed to the float but may be connected in an suitable manner, on thepipe 2 is fasten a clamp strip 16 by means of the bolts 17, a hole being drilled in the ends thereof and a. pin inserted to form a pivotbearing 18, the rod 19 connected thereto and inserted through the voke15 with the nut 20 and lock nut- 21 to adjust the extreme loiyeringposition of the float and pipe A precipitator of the ordinaryconstruetion Q is placed in any convenient place, the piping 23connectingthe vertical pipe 2 and the receiving connection 2-1 of theprecipi tutor to carry 03 the or substancewhichrisestothesurfaooinasteamgmerato e tor.
